"Though they may put a pep in your step, energy drinks can wreak havoc on your smile. The acid from them erodes the enamel and exposes the dentin, which is what makes your teeth look yellow. Studies show that energy drinks do eight times more damage to tooth enamel than drinking soda."

2.True or false: The more you exercise, the less quickly your body ages.

TRUE

FALSE

"This is false. While regular exercise has many, many benefits, athletes who overdo it may suffer from depressed immune systems, osteoporosis and reproductive health problems -- all of which can make someone look and feel older than their years. Keep in mind that moderate levels of exercise actually SLOWS aging by boosting memory, improving strength and flexibility and keeping your heart healthy."

3.It's dinnertime, and you want to boil water for pasta. What temperature water do you start with?

Hot

Cold

Warm

Doesn't matter

"Start with cold water whenever you're cooking, rinsing fruit or veggies or mixing baby formula, Warm or hot tap water can contain higher levels of lead, which can lead to memory loss. Your brain has lots of little blood vessels that act as shields, but lead can cross this barrier. Once inside, it damages the neurons and kills them. Over time, this causes the brain to shrink. Lead from tap water can also cause kidney disease and high blood pressure."

4.What's the best way to prevent energy drinks from staining teeth?

Sip them through a straw

Drink them quickly

Drink them only after a meal

"Acidic drinks such as soft drinks, fruit juices and energy drinks can cause tooth erosion, which affects the enamel and coloring of your teeth. While eliminating acidic drinks is the best defense against erosion, drinking through a straw is the next best solution. Just make sure you don't swish the drink around or hold it in your mouth for long periods of time. Talk to your dentist about your habits, and come up with a prevention plan to protect your teeth."

5.Which of the following can leave you with poor posture?

Driving long distances

Doing too many backbends

Sleeping on your side

Texting too much

"Texting too much can cause a forward head posture, which can make you look like a hunchback! Your head weighs about 10 pounds. When you lean your head forward -- as most people do when they text -- you put a strain on the joints and muscles in the neck. The more you text, the greater the strain."

6.Brrr -- it's cold! Which should you do: crank the heat in your home or put on some extra clothes and snuggle under a blanket?

Turn up the heat

Put on extra clothes

"If more youthful-looking skin is what you want, you're best off piling on the layers instead of turning up the thermostat. That's because heating systems can rob moisture from indoor air, which can lead to dry, cracked, wrinkled skin."

7.For posture-friendly texting, what should you do?

Hold your phone lower

Keep your elbows in line with your shoulders

Do neck rolls before and after you text

All of the above

"Hold your phone higher when you text, making sure your elbows are in line with your shoulders."

8.Licking the knife clean after spreading peanut butter on your sandwich can tack on how many calories?

10 calories

40 calories

60 calories

80 calories

"Believe it or not, that lick can net you an extra 80 calories! And 80 calories extra a day adds up to an extra eight pounds of weight gain in a year. Be mindful of such seemingly harmless tastes, sips and nibbles, and your waistline will thank you."

9.Why does weight gain age you prematurely?

It can raise your blood pressure

It can raise your risk of heart attack

It can cause memory loss

All of the above

"All of the above. When you carry excess weight you're more likely to have high blood pressure and a higher risk of heart attack. New data from a study using animals suggests that overconsumption of high fat foods can damage or alter the blood-brain barrier, which decreases brain function and leads to potential memory loss."

10.True or false: "Beauty sleep" is a real thing.

TRUE

FALSE

"This is true. While we sleep our bodies release growth hormones, which fix damaged tissues, including the skin. So if you skimp on sleep, you shortchange yourself on these repairs and cause your skin to age prematurely."

11.What can make you four times more likely to die prematurely?

Coming home angry every night

Playing computer games for hours

Eating salty food

Avoiding confrontation

"It pays to speak your mind: If you don't like how your partner is handling plans or a conflict, staying clammed up can cost you. Staying mum makes you four times more likely to die earlier than your peers."

12.How much vitamin D should you get daily to stave off premature aging?

500 international units

1,000 international units

1,500 international units

2,000 international units

"According to doctors Oz and Roizen, you're going to need a supplement to get enough vitamin D per day. That's 1,000 international units a day, or 1,200 if you're a woman over age 65. Vitamin D is not just good for bones and immune system, it may also help your heart. Population studies have shown that people low in D have increased risk of heart disease, but clinical studies of whether D supplements lower risk have been inconclusive."

13.How often should you wash your face if you have oily skin?

Once a day

Twice a day

Once every other day

Only at night

"It's all about balance when it comes to oily skin. In general, using an oil-free, non-comedogenic foaming cleanser that contains salicylic acid or benzoyl peroxide twice a day is best to prevent breakouts. Keep in mind that sometimes over-washing your face can lead to increased oil production, so work with your dermatologist to find a skincare routine best for your needs."

14.When is the best time to wash your face?

In the morning, right after you wake up

In the afternoon, after lunch

At night, before bed

"Evening is the best time to wash your face. Your skin is more likely to need cleaning after exposure to the elements and dirt all day, and you'll want to remove makeup."

15.Which of the following is a smart face-washing move?

Moisten your face with lukewarm water.

Work your cleanser all over your face, going up and into the hairline.

Massage the cleanser gently into skin for 30 seconds to a minute.

All of the above

"All of the above. In addition, use your fingers instead of a washcloth, and gently pat, don't rub, your skin dry with a clean towel."

16.Which body part should you also moisturize when you moisturize your face?

Ears

Nose

Neck

Lips

"When you take care of your face, don't stop at your chin. The skin on your neck can be thinner and more sensitive than the skin on your face. It's more prone to changes in pigment, elasticity and wrinkles. But there's no need to buy a special neck cream. Dr. Oz says they are just a marketing ploy."

17.After showering, you comb the tangles out of your hair while it's wet. Good move?

Yes. It's important to get the tangles out before your hair dries.

No. Doing so can damage your hair.

"Wait until your hair is dry or just damp to get the tangles out. This is because brushing wet hair can lead to breakage, leaving hair looking dull and damaged. Also, use a round brush or wide tooth comb to prevent hair loss, and hold your hair as you brush because that can prevent breakage."

18.Eating which of the following can cause you to age prematurely?

Walnuts

Flax seeds

Sugar

None of the above

"A nasty side effect of sugar is wrinkles. Also, researchers found that excess consumption of sugars can lead to higher amounts of advanced glycation end products (AGEs) in the body. AGEs are proteins or fats that are altered by reaction with sugars. AGEs affect nearly every type of cell and molecule in the body and are major factors in heart disease, diabetes and cataracts."

19.Which of the following can lead to hearing loss, even if you're young?

Listening to your iPod

Cleaning your ear out with a Q-tip

SCUBA diving

All of the above

"All of the above can lead to hearing loss. Turns out your iPod can pump over 100 decibels, and long exposure to sounds at or above 85 decibels can damage your ears. Q-tips are among the worst things for your ears because people can puncture their eardrums by mistake. SCUBA diving can rupture the membranes of the inner ear, causing fluid to escape, ultimately leading to hearing loss."

20.How loud should you set your volume the next time you listen to music?

71 decibels

75 decibels

81 decibels

85 decibels

"Rock out no louder than 75 decibels, or about 70 percent of the maximum volume. You know you've turned the volume up too high if other people can hear your tunes playing through the headphones. And, if you have to raise your voice in order for the other person to be able to hear you, it's time to turn it down."
